Jedi are stupid
how did the jedi not see Order 66 coming. There was a plethora of evidence.
Clone randomly kills a jedi, he has an organic inhibitor chip removed from his head that malfunctioned. Fives also removes his chip and tells Anakin that a really big freaking plot is happening with these chips that palpatine is involved in it and everything. There just like PSHT Nah.
Then the person that secretly without the permission of the jedi or galactic senate, ordered the clone army and mysteriously died. Investigating they find out that Count Dooku a known sith lord was involved and would goto great lengths to keep his involvement a secret.
They basically know that the clones were created by the sith and even though Fives sounded like he was going crazy near the end of his life, after finding out Dookus involvement a few of the peace's should have fit together. But the jedi counsel decides ignore all of that and use the clones anyways. And they all died because of there stuidity
